About InvoiceFlow

Who we are

InvoiceFlow is a Pakistani software-as-a-service (SaaS) platform built for one specific job: helping B2B businesses in Pakistan issue FBR-compliant digital invoices that carry a real-time unique FBR invoice number and a QR code. We serve manufacturers, importers, wholesalers, distributors and corporates who now fall under FBR's digital invoicing mandate.

We want to be transparent from the start: InvoiceFlow is a new platform, and we are onboarding our very first customers right now. We are not going to invent customer counts, "millions of invoices processed" or logos we have not earned. What we can offer is a product built carefully to the current FBR specification, direct access to the people who built it, and honest answers to your compliance questions.

Our mission

Pakistan's move to mandatory digital invoicing is one of the biggest changes to hit sales-tax-registered businesses in years. The rules are technical, the deadlines are real, and the penalties for non-compliance are significant. Our mission is to make compliance simple, affordable and stress-free for Pakistani businesses, so that issuing a valid FBR invoice is no harder than issuing the invoices you already produce today.

The FBR digital invoicing mandate in brief

Digital invoicing is not optional for sales-tax-registered persons. The framework comes from Section 50 of the Sales Tax Act 1990 and Chapter XIV (Rules 150Q to 150XQ) of the Sales Tax Rules 2006, which were substituted by SRO 69(I)/2025 dated 29 January 2025. Rule 150Q defines who is an "integrated person".

The phased go-live dates were set by a chain of SROs, each superseding the last: SRO 709(I)/2025, then SRO 1413(I)/2025, and currently SRO 1852(I)/2025 dated 24 September 2025. Under the current SRO:

In effect, all sales-tax-registered persons are in scope by the end of 2025 — not only firms above PKR 100 million. A 2026 update, STGO 01 of 2026, also confirmed that e-invoices can be edited or cancelled only within a 72-hour window, and that FBR now permits multiple licensed integrators.

On penalties, it pays to be clear about the exposure. Under the Sales Tax Act 1990 (with penalty provisions strengthened by the Finance Act 2024), FBR can impose a penalty of PKR 500,000 for a first default for failing to integrate with the digital invoicing system, escalating for repeated defaults up to PKR 3,000,000. There is also the possibility of sealing of business premises under Section 40C of the Sales Tax Act 1990. This is general information, not tax or legal advice — confirm your obligations and the exact amounts with FBR or a qualified tax advisor. Enforcement notices began reaching corporates and importers in late 2025, with broader enforcement from January 2026.

How InvoiceFlow connects to FBR

This is the part that matters most, so we want to describe the real data flow plainly. There is no magic — just a clean, secure connection to FBR's official gateway.

1. You create an invoice in InvoiceFlow. You enter (or import) your invoice details exactly as you would normally — buyer, items, quantities, tax, totals.
2. InvoiceFlow submits it to FBR's official PRAL gateway API. PRAL — Pakistan Revenue Automation (Pvt) Ltd — is FBR's IT arm and operates the Digital Invoicing system. Your invoice is sent to FBR's Computerized System through PRAL's official gateway API.
3. FBR's system returns the unique FBR invoice number in real time. This is Pakistan's legal term for what is colloquially called the IRN. (Note: "IRN" is technically the Indian term; the correct Pakistani term is the unique FBR invoice number.) The live value is around 22 characters — for example, an illustrative sample value looks like 7000007DI1747119701593. (This is a sample format shown for illustration only, not a real issued invoice number.)
4. You print the QR code. InvoiceFlow generates the QR code from that unique FBR invoice number per the PRAL specification, and displays it alongside the required FBR Digital Invoicing logo, so your printed or PDF invoice is compliant.

To be precise about what this means: InvoiceFlow submits invoices through FBR's official PRAL gateway API. We are the software that prepares your invoice, sends it to that gateway, receives the response, and produces a compliant document for you.

Security and data handling

• All communication between your browser, InvoiceFlow and FBR's PRAL gateway takes place over encrypted HTTPS connections.
• Your registration is protected by Google reCAPTCHA, and your account is created through our API.
• We use your business and invoice data only to deliver the compliance service — preparing, submitting and recording your FBR digital invoices. We do not sell your data.
• You retain ownership of your own business and customer data.

What we are NOT

Honesty here is something we treat as a competitive asset, so please read this carefully:

• InvoiceFlow is not affiliated with, certified by, or endorsed by FBR or PRAL. We are an independent private company.
• InvoiceFlow is not on FBR's official list of licensed integrators, and we do not claim to be "FBR-certified", "PRAL-certified" or "a licensed integrator". What we do is submit your invoices through FBR's official PRAL gateway API.
• We are not tax advisors or legal advisors. We do not determine your tax position or your filing obligations.

Note that integration with FBR can be done through a licensed integrator or directly through PRAL (which PRAL offers free of cost). InvoiceFlow is a tool that helps you produce and submit compliant invoices; the choice of how you integrate remains yours.

Why businesses can rely on us

• InvoiceFlow is built to the current FBR / PRAL Digital Invoicing specification, including the unique FBR invoice number and the QR code requirements.
• The rules are changing quickly — SRO 69(I)/2025, the SRO chain ending in SRO 1852(I)/2025, and STGO 01 of 2026 are recent examples. We track these changes and keep InvoiceFlow updated as the SROs, rules and PRAL specifications evolve.
• You can start with a 7-day free trial — no credit card required. We offer Starter, Business and Enterprise plans (PKR per month, billed monthly or yearly), with payment via bank transfer, EasyPaisa or JazzCash.
• Because we are onboarding our first customers, you get direct, responsive support from the team building the product.
